ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Make sure you stay aware of the following graphic client issues:

You could post a thread about here: https://www.orbiter-forum.com/forums/orbiter-visualization-project.16/ since it deals with graphics clients for Orbiter such as the currently used D3D9Client.
I think there's a bug either in the SSV Mission Editor or SSV itself as I can't get the payload retention latches to line up with the actual pins on the SpaceHAB SRM. Visually the module is in the correct location but not the latches themselves. PL IDs are 214 for the FWD trunnion pins and 238...
Anyone else have problems with getting this add-on to work: Space Shuttle Ultra SRB Sound v1.2? I have a problem where the sustain sound won't play at all in Orbiter, it's just silent while the ignition sound plays perfectly.
Yes and it's the same with the HUD guidance diamond, it's very "nervous" and never really smooths out. I think it comes down to it seems to be that both are very "digital" in that there's a lot of on/offs which causes the instantaneous jumps to new positions. So implementing some kind of filter...
Lose it, unless you're visiting some really sketchy sites, Windows Defender is more enough to keep you safe. Never had an in issue with it in the 17 years I've been using it.
Two things I've noticed with the aft flightdeck VC positions:
*On the orbiters that have guards inbetween the C&W Parameter Select wheels, the last digit is very hard to see. I've included a screenshot showing the issue on Discovery.
*The right overhead window view isn't centered which makes it...
Yes and this is perfectly normal and expected, even for the OMS-2 burn. They frequently updated the TIG based on the actual ascent performance as well as day of launch tracking of the rendezvous target. So don't ever feel bad about updating the burns after you just completed a burn.
Yes, it removes all of the intermediate files that are created during a build process. Those are used to speed the process up in the future and can fail a build process if they're outdated like yours are now.
